Background:
In conditions of industrial animal husbandry, it is necessary to pay attention to the immune system, which regulates metabolic processes in the body of animals. To do this, additives with adaptive properties attract attention.
Aim:
The aim is to define a way to increase productivity using adaptogens of plant and animal origin in feeding cattle.
Methods:
In the farms of the Orenburg region and the Republic of Bashkortostan, which differ in climatic conditions, scientific and economic experiments were done on Kazakh white-headed bulls and first-calf cows of black-and-white breed, whose diet was introduced in the form of tinctures (at the rate of 0.01 ml of tincture per 1 kg of body weight) adaptogen may change (for animals of the II experimental group), drone homogenate (experimental group III) and pantocrine (experimental group IV), while the animals of group I were assigned to the control group and did not receive additives.
Results:
The results of the evaluation of the live weight of bulls by age periods indicate that young animals consuming plant adaptogen exceeded control peers by 18 months of age by 18.60 kg (3.72%); animal origin – by 28.50 kg (5.71%; P
